High Performance Instrumented Airborne Platform for Environmental Research (HIAPER)

HIAPER（用于环境研究的高性能机载仪器平台）项目由一架高度改装的湾流V （GV）飞机组成，该飞机具有高海拔、长持续时间、大载荷能力和高速飞行能力。HIAPER飞机旨在填补国家科学机载平台机队中的一个重要空缺，并将随时和定期地允许比学术研究界通常可用的更高高度和更长时间的科学有效载荷任务。

The HIAPER (High-performance Instrumented Airborne Platform for Environmental Research) project consists of a highly modified Gulfstream V (GV) aircraft capable of high altitude, long duration, large payload capability and high speed flight. The HIAPER aircraft is intended to fill an important niche in the national fleet of scientific airborne platforms and will readily and regularly allow higher altitude and longer duration science payload missions than those generally available to the academic research community.
